HYDROCARBQN-BURNER.

QPEGIFICATION forming part of Letters Patent 742,629, dated October 27,1903. Application filed January 15,1903. Serial No. 139.100. (No model.)

To all whom it may concern:

Be it known that we, JOHN B. GORRELL and HIRAM V. GORRELL, citizens ofthe United States, residing at 'Laotto, in the county of Noble, in theState of Indiana, have invented certain new and useful Improvements inHydrocarbon-Burners; and we do hereby declare that the following is afull, clear, and exact description of the invention, whichwill enableothers skilledin the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form partof this specification.

Our invention relates to improvements in hydrocarbon-burners speciallydesigned and adapted for domestic use and for the generation of steam.

The primary object of our present invention is to provide an improvedhydrocarbonburner adapted for the perfect combustion of petroleum ,orother fuel-oils for domestic and other purposes.

In the accompanying drawings similar reference-numerals indicate likeparts throughout the several views, in which- Figure 1 is a plan view ofmy invention, broken away in part. Fig. 2 is a cross-section of thesame, showing the relative arrangement of the operative parts. Fig. 3 isa fragmentary enlarged .detail of the retort, showing the perforatedplate'used in sepa rating the fuel-chamber from the fuel-oil chamber.

We have illustrated our invention as applied to an ordinaryheating-stove, though it may readily be adapted for use in any properfurnace or other situation in which a burner can be employed.

Our improved burner consists of a hollow shell or casing having inletand outlet draftopenings and a central draft-opening and provided withan annular retort adjacent to said central opening having a liquid-fuelchamber and a generating or vapor chamber provided with anon-combustible absorbent and a deflecting-plate so fixed above saidcentral opening and said retort as to radiallydeflect the draft of saidcentral opening across the top of the combustion-chamber during theprocess of carburization and means for supplying the liquid fuel to thefuel-chamber.

The burner is mounted in any suitable manner upon a proper base 1 (shownin the accompanying drawings as a common form of base for aheatingstove) and is provided with a plurality of vertical inletdraft-openings 2 and consists of a circular plate 3, provided upon itsupper edge with an inwardlyprojecting horizontal flange 4,.to whoseinner edge is rigidly fixed the open-topped semicylindrical trough-likeretort 5, adapted to contain fragments of fire-brick or othernoncombustible liquid-fuel absorbents 6, which are so arranged in theretort-chamber as to leave an annular oil-space 7 directly beneath thefire-brick G and into which the oil is fed from any proper tank or othersource of supply in any proper manner, as by an inlet-pipe 8, controlledby a feed-valve 9. The vaporchamber 15 is separated from the oil-chamber7 by means of an annular perforated plate 12.

The retort 5 may of coursebe cast integral with the said plate 3 andflange 4,if desired.

A circular ooncavo-convex deflecting-plate 10 is arranged directly abovethe retort 5 and the flange 4 and slightly out of contact therewith,being supported in that position by means of a plurality of pendent lugs11 on the lower face of the deflecting-plate and which rest upon theinner edge of the retort, as shown in Fig. 2, thereby providing anannular draft-opening between the open top of the retort and thedeflecting-plate and also between the flange 4 and the deflecting-platefor the purpose hereinafter described.

The flange 4 is provided with a series of vertical draft -openings 13adjacent to the outer edge of the retort, as shown in Fig. 3. Theoperation of our invention thus described is obvious and, brieflystated, is as follows: The annular retort 5 is provided with a properquantity and arrangement of non-combustible absorbent material, leavingan annular oil-chamber beneath the same, into which the fuel-oil is fedeither by gravity,by air-pressure in a wellunderstood manner, or by anyother proper manner, discharging into the said chamber through theinduction-pipe 8 or any other suitable means. By lighting the saturatedmaterial in the retort 5 the heat thereof will continuously anduniformly convert the contents of the fuel-oil chamber 7 into aninflammable fuel-gas in the retort, the flame being constantlymaintained by the upward circulation of air through the verticalopenings in the base-plate 1 and the vertical openings 13 in the flange4: and also by the free circulation of fresh air through the saidopenings 2 and then through the narrow annular opening between the saiddeflectingplate 10 and the open top of the fuel-chamber, therebyconstantly forming an admixture of oxygen with the gas generated in andarising from the fuel-chamber.

The circulation of air through the burner in the process of generationis indicated by arrows in Fig. 2.

Having thus described our invention and the manner of employing thesame, what we claim as our invention, and desire to secure by LettersPatent, is-

l. A hydrocarbon-burner consisting of a hollow cylindrical casing closedupon its lower end bya perforated base-plate, and provided upon itsupper end with a horizontal flange having a central opening; a pendentannular retort fixed t0 the inner edge of the said flange and arrangedin the opening, and having a fuel-oi] chamber and a superimposedvaporchamber separated therefrom by an interposed partition; and adeflector plate arranged above the retort and adapted to direct theflame radially therefrom.

2. In a hydrocarbon-burner the combination of a cylindrical casinghaving upon its upper edge a horizontal annular perforated flange; abase-plate closing the bottom of the casing and provided with a seriesof draftopenings; a pendent annular retort fixed to the inner edge ofthe flange, leaving a central outlet draft-opening, and having afuel-oil chamber and a superimposed vapor-chamber separated therefrom byan interposed perforated partition; and a deflector-plate arranged abovethe retort and adapted to direct the flame radially therefrom.

3. The combination of a generator consisting of a hollow casing, abase-plate closing the bottom of the casing and provided withdraft-openings, an annular plate closing the top of the casing; and anopen-topped retort secured to the inner edge of the annular plate, andhaving a lower chamber for the liquid fuel, and a compartment separatedtherefrom for the vapor-chamber; and a deflector-plate so mounted on thecasing as to direct the ascending draft radially across the top of thevapor-chamber.
